Why HN links it
HN readers link this blog for its critique of Khan Academy-style video lectures, arguing that clear lectures can give an illusion of understanding, and for the idea of pseudoteaching.

What Hacker News says?
Awesome to hear! Can you give us any information on how their grades have developed? Of course, kindling fun and excitement for education and science is already a great, if not the most important, achievement. But I'm curious about the effect, that was discussed here before [1]. Derek Muller claims [2], that these videos give a false illusion of understanding. If I get him right: If your kids don't feel a bit confus…

HN discussionYou should know that "what students like" and "what constitutes effective instruction" can be very different. https://fnoschese.wordpress.com/2011/03/17/khan-academy-and-...

HN discussionOK, I appreciate your openness to understanding my point of view. I will articulate/respond respectfully. First, some quick points: 1. I must apologize for misinterpreting "Math Wars". I though it was referring to the recent little "skirmishes" between certain math professors and Khan Academy (as found here, for example: http://www.washingtonpost.com/blogs/answer-sheet/post/khan-a... ) 2. Your tutorials sound fantas…

HN discussionI know dropping newly-learnt and vaguely-understood words loosely is generally a bad habit for people on Hacker News, but also consider the concept of pseudoteaching[1]. [1]: https://fnoschese.wordpress.com/2011/03/17/khan-academy-and-...
